Battery pack pack include four rechargeable structure

• Temperature Payment: 0o to 45oC (32o to help you 113oF) ±dos.5% precision -20o in order to 0oC and 45o so you’re able to 65oC (-4o to +149oF and you may 112o to help you 148oF) ±5.0% accuracy
• Altitude Payment: Below water-level in order to no less than 10,one hundred thousand feet.
• DIMENSIONS: 2-1/4 inches strong x 4-1/cuatro ins high x cuatro ins wide (5.eight centimeters deep x 10.8 centimeters large x 10.dos centimeters greater). Proportions are button coverage but ban hose barb and gear video.
• WEIGHT: 23 ounce. (652 grams)
• CASE: Case vinyl is electrically conductive to minimize radio frequency disturbance; an elective fabric instance can be acquired to have
  Place for ADS
  push protection while in the rough usage such as for example below ground mining or framework and demolition performs elements
• SERIAL Count Identification: Located on the side of the circumstances according to the battery power (include amount inside correspondence which have Zefon)

Functional Breakdown away from Operation

The fresh new Companion ELF Pump includes a rechargeable battery package, a motor-motivated push, this new ELF detector, therefore the electronic circuit to deal with and you can monitor the fresh new circulate speed.

This new cells are linked in the series having a recently available restricting resistor to allow use in hazardous atmospheres (get a hold of “Warnings”). The brand new prepare likewise has an effective PTC resistor and this functions as good self-resetting routine breaker to cease damage to the newest prepare if for example the efficiency terminals are happen to shorted. A thermal cutoff handles facing destroy of high heat criteria inside the new NiMH electric battery.

Brand new motor-passionate pump include a keen inlet pulsation dampener, good diaphragm pump, and you may silicone polymer rubberized inlet and you will deplete regulators. The fresh new diaphragm is motivated of the motor and work out you to push stroke with every revolution. The newest pulsation dampener acts as an elastic stores chamber in order to simple the individual push pulses to reduce the impact on brand new sampling devices connected to the pump inlet.

The ELF alarm includes a laminar flow feature and you may good tension sensor. The air flow from the pump seats on the exhaust port of your own push and you can from laminar-flow ability. The brand new element is a hollow cylinder from permeable stainless. The air streaming through the slim verses from the cylinder provides an environment pressure difference between the fresh outer and you may interior walls of the new tube. Which variation try tracked of the connections to the brand new higher and you may reasonable stress taps away from a sensitive differential pressure alarm. The latest electronic rule from the alarm was a linear current, that’s privately about air flow through the laminar element. Which rule is actually compared to circulate set reason for the fresh new digital routine which is regularly handle the brand new circulate from the set part. One departure inside disperse rate is actually felt and also the engine electricity are modified to keep up the newest preset flow rate. In the example of a clogged disperse otherwise operation not in the pump capability where flow cannot be delivered to within this ±0.1 LPM of your lay point, top article new move blame Contributed was lit.

Led Indication Process

• The fresh new Run/Keep Led assurances the consumer your product is working, even in defectively lit, noisy surroundings.
• The fresh Run/Keep Contributed plus suggests the fresh Hold form. In case the push are transformed to hang, the latest pump closes down, the fresh timer finishes, in addition to Provided was transformed in order to a flashing means. In the event that Work at/Hold option was forced once more, this new push often restart and also the timer will continue from the “hold” well worth.
• The lower BATT Led indicates process of the low power supply identification routine. If the battery pack falls so you’re able to cuatro.step 1 volts, brand new circuit causes this new push to close off down, new timekeeper to avoid, together with Lowest BATT Resulted in light. That it restrictions next electric battery sink just to a number of milliamperes, and this, subsequently, aids in preventing strong discharging and you may battery pack wreck through to charging. It also helps prevent the invalidation of your try becoming removed, due to the fact timekeeper locations the actual test some time and the fresh new disperse price try controlled around the amount of time out-of sealed-off.
